Service Manual (internal version) SIPLACE HF and X Series 63
► Position the guide device (5) at a suitable distance to the hole on the guide rail (6) and fix with the
screw.
► Pull the transparent cover strip off completely.
► Pull the fixing pin (3) out of the adhesive device (2).
► Place the adhesive device (2) onto the guide rail.
► Insert the fixing pin (3) into the adhesive device (2) so that the scale runs between the guide (1) and
the pin (3).
► Wrap the transparent cover strip from the adhesive strip around the fixing pin.
► Slowly pull off the transparent strip; press down the rollers of the adhesive device and fix the whole
scale as far as possible (up to the gantry).
► Remove the adhesive device and move the gantry so that you can fix the rest of the scale.
► Change the adhesive device and finish fixing the scale completely.
► Press the rest of the scale down with your hand and with the help of a tear-resistant cloth.
► Remove the centering pin from the left side of the scale.
► Clean the scale with a cloth and ethanol.
► Clean the reading surface of the incremental encoder with a cloth and ethanol or with a SIPLACE
cleaning tip [00352931-xx].
► Fit the incremental encoder with the three fastening screws so that there is a gap of 0.4 mm between
the incremental encoder and the scale. Use the corresponding thickness gauge (plastic).
► Check the track signals.

CAUTION
Set the fixing pin correctly
The fixing pin for the scale must be set so that it touches the screw and can guide the scale,
without the latter slipping out.

NOTICE
Damage
If the blue cover is damaged (kinks, cracks etc.), replace it during reinstallation. White or pale
patches in the plastic indicate areas of damage.
WARNING
Risk of serious injuries through trapped limbs.
Please take special care when working in the vicinity of the powerful magnetic fields produced
by the magnetic strip.
► Carefully rub the contact surfaces (1) of the magnet
with a dressing stone (oil stone) and wipe clean with
a cloth and ethanol.
► Fit the magnetic strip (2). Make sure that there is a
gap of 0.8 mm between the individual magnetic
strips.
► Tighten the screws to a torque of 9.5 N.
► Check the blue cover for damage and replace if nec

3.3.8 Replacing the Y Linear Motor Secondary Part (Magnets) Gantries
Service Manual (internal version) SIPLACE HF and X Series 65
► Attach the blue cover to the fastening screws.
► Knock the cover into place with a rubber mallet and block of wood.
► Move the gantry to one side.
► Hook the notch of the magnet cover plate (3) approximately in the center (4).
► Move the gantry over the magnet cover.
► Pull the magnet cover with the aid of a second strong person on both sides and hook in at both ends.
► The magnet cover must lie flat on the magnets. You should not see any unevenness e.g. buckling,
waves.
Installation check
Settings
► Check the axis dynamics of the drives removed.
NOTICE
Sanding off the cover
Production tolerance could mean that the cover will not lock into place. In this case, sand off a
little of the cover upper edge.
CAUTION
Take care that the cover and the magnetic strip are correctly positioned!
The cover must be sit lower than the magnetic strip.
► Move the gantry back and forth. Make sure the gantry
does not rub against the magnet cover or the blue
covers (1).
► Check the 0.4 mm gap between the Y axis drive and
the magnet cover.
► To do this, place the thickness gauge (2) between the
Y axis drive and the magnet cover and then push the
gantry back and forth.
Make sure none of the parts jam or rub.
► Repeat this procedure with a 0.5 mm thickness
gauge. In this case, the gantry may rub against the
warning label.
► Clean the magnet cover with a cloth and ethanol.
► If the gap is not large enough, you will need to remove
the magnet cover and clean everything again.
⇨ Remove the magnetic strip and clean the contact
surface
⇨ Check the blue cover
